====== Electrical terms often seen with solar ====== * **I** - current in Amps. The //I// comes from the archaic term //intensity//. * **Imp** current at the panel's maximum power output (see Vmp) * **Isc** - Amps when short circuited; this is when your [[electrical:solar:panels|solar panels]] are connected only to themselves. This is the highest current your panels can theoretically produce. * **Pmax** maximum power a panel will make. Vmp * Imp = Pmax * **[[electrical:solar:charge_controller_setpoints|Setpoint]]** - a value used to place a limit or border on a particular operation. If your refrigerator is set hold 40F temperatures then //40F is the setpoint//. If your charger floats at 13.2v then //13.2v is the Vfloat setpoint//. Setpoints may be preset by the manufacturer or configured by the user. * **V** - Volts * **Vabs** - [[electrical:solar:charge_controller|charge controller]] voltage setpoint for [[electrical:12v:charging#absorption_stage|Absorption stage]] * Vbatt - actual voltage of the battery bank. * **Vfloat** - charge controller voltage setpoint for [[electrical:12v:charging#float_stage|Float stage]] * **Vmp** - voltage at which a panel makes **m**axiumum **p**ower (watts) * **Voc** - volts in open circuit; when your [[electrical:solar:panels|solar panels]] are not connected to anything. This is the highest voltage your panels can theoretically produce. * **Vpanel** - voltage the controller is running the panel[s] at * **W** - power in Watts
